Title: Mass flow meter
Inventor: IKEDA KIYOUICHI
IPC: G01F1/76
Filed: 1982-03-25
Abstract: PURPOSE:To enable improving of reliability and reproducibility of measurement of a  flow rate without attachment of a mass object on a pipe line, by a method wherein  one of currents, flowing through the pipe line, and a magnetic field, generating in a  direction intersecting the current, produces an alternating current and the other produces a direct current to excite the pipe line. CONSTITUTION:When an alternating current flows through a coil 8 in a current generating part 7, an alternating current (i) is induced in pipe lines 11 and 12, while a magnetic flux B produced by a permanent magnet 10 in a magnetic field generating part  14 intersects the pipe line, and thereby a force F is exerted to vibrate the pipe lines  in a direction at right angles to the magnetic field B. Fluid flowing through the pipe  lines 11 and 12 runs in a reverse direction, and thereby a current induced and a force  run also in a reverse direction, which results in causing them to vibrate in a fork-line manner facing and opposite to each other. M7 and M8 showing the vibrating pattern  of the lines are that which is excited by a driving means, while M9 and M10 are that  which is caused by a Coriolis force exerted on fluid, and a mass flow rate is obtained through detecting of deflection caused by thereby and measurement of a phase difference. This permits the high reliable measurement of a flow rate without attachment of  a mass object on the pipe lines.
